摘要: 端粒是构成真核生物线状染色体末端重要的DNA-蛋白质复合结构,DNA由简单的串联重复序列组成。它的合成由一个特殊的具有反转录活性的核糖核蛋白-端粒酶完成。端粒对染色体、整个生物基因组,甚至对细胞的稳定都具有重要意义。本文就植物端粒、端粒酶、端粒结合蛋白,以及端粒变化、端粒酶在植物生长发育中的调节作一概述。

关键词: 端粒酶, 端粒

Abstract: Telomere is an important DNA-protein structure.It caps the ends of linear eukaryotic chromosomes.Telomeric DNA consists of tandemly repeated simple sequences.Telomere is synthesized with the action of telomerase,a ribonucleoprotein with reverse transcriptase activity.Telomere plays an important role in maintaining the stability of intact chromosome,genome and cell.This paper is a review of telomere,telomerase,telomere-binding protein and developmental control of telomere change,telomerase activity in higher plant.
